Closing the clip on the Belay Master ensures the carabiner is safe for use. It can only be closed when the gate is screwed shut.
When closed, the clip keeps the carabiner in its strongest orientation, prevents devices and knots from moving onto the spine, eliminates possible cross loading due to rotation. This feature makes the Belay Master the perfect belay carabiner for those new to belaying.
